Detectability of dark matter subhalo impacts in Milky Way stellar streams
Junyang Lu, Tongyan Lin, Mukul Sholapurkar +1
Stellar streams are a promising way to probe the gravitational effects of low-mass dark matter (DM) subhalos. In recent years, there has been a remarkable explosion in the number o…
